SMOKE-CONSUMER FOR BOILER OR OTHER FURNACES.

SPECIFICATION forming part of Letters Patent No. 663,129, dated December4:, 1900.

Application filed April 30. 1900.

To all whom, it may concern:

Be it known that I, SAMUEL NOCK, a subject of the Queen of GreatBritain, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inSmoke-Consumers for Boiler or other Furnaces; and I do hereby declarethe following to be a-full, clear, and exact description thereof,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention relates to an improved smokeconsnmer for boiler and otherfurnaces; and it consists in the certain details of construction andcombination of parts, as will be fully described hereinafter.

In the accompanying drawings, Figure 1 is a side sectional elevation ofa boiler-furnace setting, showing my improved smoke-consumer arranged inconnection therewith, the same being constructed and fitted inaccordance with my invention. Fig. 2 is a sectional plan view of thesame, showing a portion of the boiler removed. Fig. 3 is a rear endsectional elevation of the boiler-setting. Fig. 4 is an enlargeddetailed elevation of a portion of the steam-jets arranged at the rearof the boiler. Fig. 5 is an enlarged detailed side elevation of one ofthe valves for regulating and controlling the admission of steam and airinto the fire-chamber.

To construct a smoke-consumer in accordance with my invention and adaptthe same for use in boiler and other like furnaces, the said furnace andsetting consisting of the boiler or steamgenerator 1, arranged in asuitable setting 2, in which is formed a firechamber 4, havinggrate-bars 6, a bridge-wall 3, fire-doors 5, and other parts well knownin the art, I form from suitable tubing a series of steam-jets 11,arranged in two rows, and locate the same at the rear of the boiler l ina position that will direct the current of steam across the rear end ofthe smoke-fines and at right angles therewith. Formed in connection withthis series of steam-jets 11 is a perforated nozzle 10, used to direct acurrent of steam toward a smoke-flue located at the opposite side of thesetting and in a direct line with the said nozzle 10. This smokeflue 15is formed with a large entrance 13 and Serial No. 15,023. (No model.)

reduced exit 14, entering the fire-chamber 4 at a point at or about thelevel of the bridgewall 3. Connecting these steam-jets 11 and nozzle 10is a supply-pipe 9, fitted with a regulating-valve 9 and incommunication with the steam-dome 7 of the boiler 1 by means of a branchpipe 8,which arrangement when the valve 9 is opened will supply steamfrom the boiler to the said jets and nozzle.

At the front of the boiler 1 is placed asteampipe 16, connected to thebranch 8, leading from the dome 7, and the said pipe fitted with aregulating-valve 17. This pipe 16 is arranged in a horizontal positionacross the front of the setting at a point above the firedoors 5 and isfitted with a series of combined inlet-valves and air-mixers, (see Fig.5,) each of which consists of a shell 18, provided with an internalvalve 21 and steam-jet 23 to regulate the flow of steam and withopenings 22 for the admission ofair, and each of the valves connected toa nozzle 19, having a perforated end 20 and arranged to project into thefirechamber 4 about the level of the top of the bridge-wall 3.

In operation the smoke passing over the bridge-wall 3 on its way to therear end of the smoke-fines is met with a counter-current of steam fromthe nozzle 10 and jets 11, which will abstract the smoke particles andforce the same into the mouth of the smoke-flue 15 and create a draft toconvey the said smoke particles back to the fire-chamber 4, where theyare consumed and the combustion of the fuel in the said chamber aided bythe admixture of steam and air from the nozzles 19.

Various slight modifications and changes may be made in the details ofconstruction and the arrangement of the parts without departing from thespirit of the invention.

Having thus described myinvention, what I claim, and desire to secure byLetters Patent, is-

The herein-described smoke-consumer for boiler and other like furnaces,consisting of the series of steam-jets arranged to direct a currentacross the rear ends of the smokeflues of the boiler, a nozzle arrangedin connection with the said jets used to form a draft toward asmoke-fine in alinement with the steam-jets and located in the oppositewall of the setting, the said flue leading from the rear of the settingto the fire-chamber, and a series of combined steam-jets 23 andairlnixers arranged at the front and leading into the fire-chamber4, allarranged and combined for service, substantially as and for the purposedescribed.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.

V SAMUEL NOOK.
